SURRA. 



This disease occurs in Northern India and neighbouring 

 parts of Asia, attacking horses, camels and cattle. It is a very 

 fatal malady, and one that carries off a large percentage of 

 horses. It is due to minute parasites invading the blood 

 stream. The organisms are known as trypanosomes — unicellular 

 animals having a whiplike process at one end. 



A remarkable feature in connection with these organisms 

 is their presence in the blood of certain rats, such as the sewer 

 rat, though they are not present in all members of this species. 



These rodents do not appear to suffer any inconvenience 

 through their presence. Such eminent bacteriologists as Koch, 

 and the late Professor Nocard, considered that surra and nagana 

 are identical diseases. 



CAPE HORSE SICKNESS. 



This is a very prevalent disease in South Africa, and there 

 is a disease practically the same in the Soudan. The most 

 favourable locahties for outbreaks of horse sickness are where 

 the land is" swampy, in^ short, malarial districts. During the 

 South African War an innnense number of horses died from

 has recovered from the disease, owing to its acquired immunity,
